I recently purchased a "not running" b6 switcher from 1989. Everything works fine except the worm gear is slipping on the axle. Has anybody had any success glueing the gear in position on the sinstered axle? Might there be other issues with the gear mesh not being correct? I was kind off surprised that the worn gear is plastic. I am not experienced with repairs, so one might ask "well why did you buy it?"; but having bought into this at a low price, I wasn't as apprehensive about messing with it, and I am learning in the process.
